Referring to the drawing, 10 indicates the container and 11 the neck thereof the outer end l 2 'being: some-what'thicker than theneck proper-'1 This is the usual practice as all necks are roundechflange'd or. thickened in some manner. In the present instance, I prefer to also form the. exterior of the neck with a re-entrantannular groove 13 and an annular rib or enlarged portion 14 directly beneath the groove 13 and this ann'ular enlarged portion is preferably terminfates ma shoulder lobetween thelower end thereof and the exterior of the neck pro er. 'Thisishoulder'is and may be verysmall 'although if for any reasonitis desirable it maybe made somewhat larger. The closure 17 has aliner 18 of cork or any other suitable material and in the application of the closure the liner18 is brought into contact with the extreme end of the neck of the As. previously state'd, the closure may be ofthe; screw typeor crimpedtype or it may be of a type in'which the fastening means is carried by the cap itself such as the clamping ring 19 and lever 20; shown in Fig. 1 ofthe drawing; V

For the purpose of. supporting the container by the neck, I employ any suitable supporting means and as one form; I have shown two. clamping jaws 21 notched M322 1 tiguous sfaces, asindiclatedat 26 and between to receive the neck ofthe bottle therebetween;

These jaws are pivoted atf23 upo'na bracket 24:;Wlll6l1 in turn is adjustably fastened tola standard 25, The opposite ends of the jaws 21: are notched or cut away upon their con,-

these, endsthere 'reciprocate's. a wedge shaped plunger 27 for the purpose of bringingthe outerends of. the jaws together for the purpose of-gripping-theneck of the shoulder anda spring--28 may be arranged between .the said jaws for the-purpose of spreading the outer ends when the Wedge shaped plunger is'withdrawn'or movedupwardly. 4

This wedge shaped plunger may be car ried by. an arm 29 adjustablysecured to a rod30, the upper end of this rod being loosely connected to .alever 31fixe'd-on a shaft 33 and actuated by a frod 32hr any other suitable actuati g m hanism; T e a rd 2 1 car ieclhor i n e y outwa 'ly s' S QW at 1- andrfor ed wi h a ou ng 5" i w ch is journaledafifshafftj33 carrying; an. arm 34,

This arm 34 en g. wing as it-Ldoes the block 36, forcessaid block downwardly, carrying with itthe rod 37 provided with theecap carrying chuck 3.8 at its lower end. The cap 17 carried by the chuck is forced upon the end of the neck of thecontainer and the continuedpressure upon the d32. causes the closure to be forced down tightly upon the neckof the container compressing the liner andefi'ecting-a tight sea The lever tripping mechanism can then be actuated or, in case the chuck is provided with .acrimping or screwing mechanism, these operations can be taking place at the same ime i e-ra me n btor e ng the pp rt ngvofthecontainer-by the neck at the reinforced orstrengthened portion thereof so thatfthe entiresealing pressure is applied to onlyj-that portion 7 of: the container neck capable of; withstanding the. same and coma so a su tab e meausfor carrying-01.1 such method.
